Pedestal or work bench should be bolted to the floor. 1. Adjust the Lower Roll to grip the metal firmly and evenly but without straining the machine. The Lower Roll is adjusted up or down with the two lower Adjusting Screws . 2. Adjust the Rear Roll to form the metal up as it travels through the rollers. The Rear Roll is adjusted up or down with the two rear Adjusting Screws . Be sure the Rear Roll is parallel with the Lower Roll. If the rolls are not parallel, the formed metal will be conical in shape instead of cylindrical. 3. Feed the stock to the rolls only from the front. 4. As the front rolls grip the stock, lift the rear end of the metal upward. This will help reduce the flat spot on the leading edge of the sheet and will also cause the leading edge to pass over the rear roll readily. 5. The diameter of the formed cylinder is determined by the position of the Rear Roll. To increase the diameter of a cylinder, lower the Rear Roll by turning the two rear Adjusting Screws counter clockwise. To reduce the diameter of a formed cylinder, raise the Rear Roll by turning the two rear Adjusting Screws clockwise. The two rear Adjusting Screws should be turned an equal number of turns in order to keep the Rear Roll parallel with the front gripping rolls. 6. To remove a cylindrical piece without distorting it, lift up the Locking Handle , raise the Right Hand Housing Cap and turn the Cam Handle down. This raises the outboard end of the Upper Roll and allows the formed cylinder to be slipped off of the Upper Roll. 7. The Lower Roll and the Rear Roll have grooves of varying widths in one end. These are for the purpose of accommodating a wired edge when forming a shape or when forming wire into a ring. NO. 416

SLIP ROLL FORMERS 416, 417, 418
Forming Machines, or Slip Roll formers, are intended for rolling sheet metal or forming cylinders ofvarious diameters.
The two pinch rolls feed the sheet against the rear roll, curving the sheet and forming the cylinder. Therear or forming roll can be adjusted by screws on the rear of left and right end housings, varying thediameter of the required cylinder. Pinch rolls can be adjusted for stock thickness by screws on thefront end of the housings.
The capacity ratings of PEXTO forming machines are based on forming mild steel, fully annealed, thefull length of the rolls and are considered as standard by the sheet metal trade for forming rolls of aspecified diameter and length. Definite capacities, however, depend upon the diameter and length ofthe cylinder to be formed and the number of passes through the rolls to obtain a given diameter.Stiffness of material and uniformity desired are also factors. When a forming machine is overloaded,the immediate result will be deflection in the center of the rolls, resulting in cylinders bulged in the center.
Three inch diameter forming rolls have longitudinal grooves in the rear forming roll to assist in startingthe sheet. Forming rolls 3” in diameter and larger have all three rolls driven as standard. Three rolldrive for rolls under 3” in diameter at extra cost.
In order to reduce the number of rear roll adjustments when sheets are of light gauge, proceed asfollows:
1. Insert the sheet between two pinch rolls.
2. Bend the sheet upwards and slightly around the top roll.
3. Continue to pass the sheet through the machine.
This will also reduce the flat spot on the leading edge of the sheet.
The right-hand housing is provided with a hinged journal cap and lifting latch. After the cylinder isformed, the latch is lifted and the lever is pressed down. This raises the top roll and the cylinder canbe slipped off the roll without distortion.
Forming machines are provided with grooves in the right end of the lower and rear rolls to allow forforming cylinders with a wired edge.
WARNING: Before operating, machines must be bolted to the work bench. If the floor stand hasbeen provided, machine must be bolted to the floor stand with bolts provided. Standmust be securely lagged to the floor.
